Comment 79 for bug 438536

I agree with ex-oficio. The notification should just be a stack. Actually, I thought it was a bug because I was using the beta release.
Maybe some notifications, like volume or brightness, could have more important priority, so that if they are thrown after a simple notification (like one of Rhythmbox), they would appear at the top of the stack while the other notification simply appears at the bottom.

This offset is definitely not normal!
